drawings representing like parts.

This invention has for its object the productlon of a machine for the manufacture of continuous bundling wire or a wire bent upon itself at desired intervals to form a series of loops or eyes, such wire being useful in securing bundles, the loops or eyes greatly aiding in applying the wire tightly to the articles to be packagedor held together,and also furnishing convenient means by which to secure the ends of the bundling wire when passed about such articles.

In accordance with this invention, I provide suitable devices for acting upon and looping the wire and twistingthe loop to form an eye.

In the preferred form of machine, the wire is grasped by a twisting hook mounted upon the end of a sliding and rotary spindle, the spindle and hook being moved longitudinally toward and from the wire to grasp and loop the same, and rotated to twist the loop held upon the hook to form an eye, the twisting hook then discharging the loop or eye, after whlch the wire is fed a greater or less distance and is again grasped and twisted.

Figure 1 is a front elevation of a wire twisting machine embodying my invention with one flangeof the reel removed; Fig. 2, a section to the left of the dotted line a;-0c in Fig. 1; Fig. 3, an enlarged section to the left of the dotted line w'w', Fig. 1; Fig. 4, asection below the dotted line 50 Fig. 2. Fig.5 shows a piece of wire when looped by longitudinal movement of the twisting hook. Fig. 6 shows a piece of the completed bundle wire provided with the twisted eyes. Fig. 7 is a vertical section of the reel taken on the line w -w Fig. 1, both flanges being shown. Fig.

8 is a side view of the ratchet plate detached;-

and Fig. 9 is asection below the dotted line av -120 Fig. 2, with the twisting hook omitted.

Referring to the drawings, inthe construcrepresents a table mounted upon suitable legs'A', and said table has secured to it the base B of the twisting machine, said base having an upright B provided with suitable bearings, as B for the spindle B loosely connected atits upper end with a lever B pivoted at B on anlear of. the upright, said lever having, as shown, at its front end suitable pins or pro jections 2, which enter from opposite sides a groove 5 in a block or collar a fastened to or forming a part of the upper end of the spindle. The'spindle B is surrounded between the bearings B bya sleeve B ,said sleeve being splined to said spindle bya spline 6, in order that. the spindle maybe raised and lowered longitudinally within said sleeve. The lower end of the sleeve B is provided with a beveled gear b, which is'engaged bya larger beveled gear I); fast on a rotating shaft b adaptedto be rotated by power, manual or otherwise, but herein shown as manual, by means of a crank handle h The lower end of the spindle, as herein shown, is provided with a wire twisting device g, shown asa hook, connected with the spindle by. a pivot said hook being normally retain ed in its position shown in Fig. 3, by a spring g. The spinsleeve B by the lever B and the rhd D extended preferably through a suitable treadle D upon the floor. The wire to, which is to constitute the bundling wire, and which is to be twisted, will in practice be taken from a suitable reel or cop, not shown, and led through suitable wire straightening devices O, of usual or desired construction, herein Shown as consistingof a number of rolls or pulleys, between which the wire is drawn, the straightened wire, issuing from said devices, being led across the throat d, in a suitable groove in the latter, and under the bridge d, said throat having an opening (1 below which in the bed-plate B' is provided a pocket 0. After the wire leaves the throat, it is passed in the first instance about a measuring device E, shown as a disk provided with a poripheral groove e,in and about which the wire dle may be raised and lowered within the is passed one or more times, preferably once,

after which it is led to the receiving spool or upon which it is wound until ready for use.

In the present instance, and preferably, the circumference of the base of the groove in the periphery of the measuring device, is equal to the distance between two adjacent eyes in the completed bundling wire, so that each rotation of the measuring device represents a feed of the wire sufficient to carry it from one eye to another duringthe formation of the eyes. The measuring device or disk is secured upon to rotate with a shaft 6 journaled in a suitable bearing e properly supported by the frame, the said shaft, as herein shown, at its rear end having secured to it a ratchet plate 6, shown separately in Fig. 8, with which cooperates a suitable detent e, which latter by dropping into the notch e in the ratchet plate retards the rotation of the measuring device and indicates to the operator whenever the measuring device has made one complete revolution. The bed plate B has mounted upon it a hold-down f, the same having a sliding movement, it being pushed forward to overlap the wire to during the twistingoperation, and thereafter drawn back to permit the feed of the wire with the loop or eye formed in it, a slot f in the hold-down entered by a screw 8 permitting such movement. The hold-down is moved preferably by an elbow-lever f, and a link f attached at one end as at f to the lever B, and slotted at its opposite end to embrace a pin 7 on the elbow-lever, the hold-down being pushed forward over the wire immediately before the spindle rises. Spring g acts normally to lift the treadle and depress the spindle. When the spindle is in its depressed position, the hook which constitutes the twisting device, occupies a position in the pocket 0 and below the wire w as shown in Fig. 3, the inclined side wall c of said pocket holding the hook in its rear or abnormal position against the action of the spring 9 The operation of the machine is as follows, viz:-The operator by depressing the treadle, lifts the spindle and hook, the latter, as soon as it leaves the inclined surface 0", being moved to the left by the spring 9 into position directly beneath the wire, which latter it engages as the spindle is lifted, and bends the wire into an inverted U-shaped loop (see Fig. 5) between the bridge (1' and the holddown f. The handle 19 is now turned to retate the spindle with its attached hook hold: ing the loop thus formed, and thereby twists the loop upon itself and about the hook one or more times, to form an eye, as shown in Fig. 6. The treadle is then released to lower the spindle, the inclined under side g of the hook, as the latter is lowered, striking the bottom of the eye just made and being thereby forced to the right out of engagement with the eye, the latter being retained in its upright position and from following the hook as it retreats, by means of two inwardly projecting pins or projections 9 and 10, upon the inner faces respectively of the bridge and hold-down (see Figs. 4 and 5), further movement of the spindle bringing its hook into contactwith the inclined face c of the pocket 0, thereby throwing the hook to the right sufficient to clear the eye when the wire 1s fed forward. The operator now rotates the reel which constitutes a wire-feeding device by means of a suitable handle applied to the squared end of its shaft to draw or feed the wire forward through the machine preparatory to the formation of a new eye, the w re being drawn forward until the detente which has been raised by the inclined rear edge e of the notch e drops into the notch again when the ratchet plate c has made one revolution, indicating that the measuring device has made one complete revolution, and has therefore fed the wire the proper distance between two adjacent eyes, when the feed is stopped and another eye formed in the wire, as in the manner hereinbefore set forth.

It will be noticed that the axis of the measuring device E is not perpendicularto the direction of feed of the wire, but stands at an angle thereto, so that the wire having the eyes formed in it, as it. passes about the groove in the peripheryof the measuring device, will pass about the same spirally, so that an eye in the wire having passed about the device and rising upon the back side thereof, will stand atone side of and thereby clear the wire leading to the measuring device from the eyeforming mechanism, so that said eye will not,

interfere with the proper feeding of the wire.

I have herein shown and prefer to employ a peculiarly constructed reel which is the receiving and feeding device in order to facilitate the removal of the cop when the reel is full.

Referring to Figs. 1 and 7, the reel consists of acore F provided with two end flanges F F one of which, as F is removable, and in Fig. 1 said flange is supposed to be removed.

Asplit sleeve,preferablyin the form of a thin steel plate m, surrounds the core F of the reel, said sleeve having a V-shaped depression m formed at one side and having its abutting ends m turned inwardly at the opposite side of the core to thereby support the sleeve always at a distance from the core and retained thereupon solely by the friction at the points m and m filled with the completed bundle wire, the movable flange F (see Fig. 7) is taken off and the cop and sleeve m slipped from the core, this being easily done by reason of the slight When the reel has been friction between the points on and 'm of the herein shown to illustrate this invention, for it is evident that the same may be varied in many particulars without departing from the spirit and scope of the invention.
